Re: [Q] figuring out a system / source file

I defined variables which show current component and current system. They can be used by IDEs to navigate to sources, or by your code to do what you need. I suggested this as a modification of asdf, but asdf maintainers said that special variables are dangerous. Maybe. My code is here: https://bitbucket.org/budden/budden-tools/src/default/asdf-3.1.4-tools.lisp?at=default&fileviewer=file-view-default
